Sirtuin 1, or SIRT1, is known to play an important role in maintaining metabolic balance in multiple tissues, and studies in various organisms have shown that activating the protein can lead to many health benefits. Also, drugs that increase SIRT1 activity have been found to slow the onset of aging and delay age-associated diseases in several animal models.

Researchers led by Dr. Rafael de Cabo of the National Institute on Aging at the National Institutes of Health tested the effects of a small molecule that activates SIRT1, called SIRT1720, on the health and lifespan of mice. The animals were fed a standard diet supplemented with 100 mg/kg SRT1720 beginning at 6 months of age for the remainder of their lives.
